Technical Abstract

A directory deletion method and apparatus, and a storage server, where the directory deletion method includes receiving, by a storage server, a delete operation authentication request of a host, where the delete operation authentication request carries user information and information about a target directory, storing, by the storage server, the user information and returning a file identifier (FID) of the target directory to the host after authentication succeeds, sending, by the host to the storage server, a delete request carrying the FID, performing, by the storage server, verification on the file and the subdirectory using the user information, and deleting a successfully verified empty subdirectory and a successfully verified file. Hence, the directory deletion method and the apparatus, and the storage server improve directory deletion efficiency.

Patent Claims
11 claims

Legal claims defining the scope of protection, as filed with the USPTO.

4

4. The directory deletion method of claim 1, wherein a create operation flag has been set for the target directory, and wherein the directory deletion method further comprises sending a failure response message to the host.

5

5. The directory deletion method of claim 1, wherein performing the delete operation on the file and the subdirectories in the target directory comprises starting, by the NAS server, a plurality of threads to perform the delete operation, and wherein each thread deletes at least one file.

6

6. The directory deletion method of claim 1, wherein performing the delete operation on the file and the subdirectories in the target directory comprises starting, by the NAS server, a plurality of threads to perform the delete operation, and wherein each thread deletes at least one of the subdirectories.

10

10. The NAS server of claim 9, wherein the instructions further cause the processor to be configured to store the correspondence by storing the correspondence in the target directory and in each level in the target directory, wherein a delete flag is not set for the target directory, and wherein the instructions further cause the processor to be configured to set the delete flag for the target directory.

11

11. The NAS server of claim 9, wherein a create operation flag is not set for the target directory, and wherein the instructions further cause the processor to be configured to set the create operation flag for the target directory.

12

12. The NAS server of claim 9, wherein a create operation flag has been set for the target directory, and wherein the instructions further cause the processor to be configured to send a failure response message to the host.

13

13. The NAS server of claim 9, wherein in a manner of performing the delete operation on the file and the subdirectories in the target directory, the instructions further cause the processor to be configured to start a plurality of threads to perform the delete operation, and wherein each thread deletes at least one file.

14

14. The NAS server of claim 9, wherein in a manner of performing the delete operation on the file and the subdirectories in the target directory, the instructions further cause the processor to be configured to start a plurality of threads to perform the delete operation, and wherein each thread deletes at least one of the subdirectories.

17

17. The directory deletion method of claim 1, wherein the directory path information of the target directory comprises an upper-level directory of the target directory.

18

18. The directory deletion method of claim 1, wherein the file and the subdirectories are deleted concurrently in a background of an operating system.

20

20. The directory deletion method of claim 1, wherein the NAS server is configured to communicate with the host using Common Internet File System (CIFS) protocol.
